Hi,
I begin my NHibernate mapping. In major cases I use int type but for some entities I need to persist million of objets. Is long type for identity will be the best choice ?
I am developing a network based application. I need to retrieve data through internet. The scenario is like this - a client machine will send data through internet to the server machine and data size will be big enough. So should i use simple TCP/IP socket concept or else? Because i never did a socket program which will retrieve data through internet..... Any suggestion will be very helpful....... Thanks.
I'm looking for a way of mapping a uid (unique number representing a system user) to a user name using Perl.
Please don't suggest greping /etc/passwd :)
Edit
As a clarification, I wasn't looking for a solution that involved reading /etc/passwd explicitly. I realize that under the hood any solution would end up doing this, but I was searching for a library function to do it for me.
Hi. Does anyone know a good C# tutorials (example) step by step?
It should be not a description of libraries, foundations and the OOP concept, and so forth, but the writing of any application step by step. For example, a mail client, telephone directory, a simple graphical editor, audio player.
Thanks!
11g and 10g both have the all_queue_subscribers (and user_, dba_) dictionary tables for listing the subscribers to queues, but this doesn't exist on 9i. Does the same concept of queue subscribers exist on 9i databases, and where can I get this information from?
we have understood the concept of fluent api but now we want to look over some existing fluent api for better understanding.
where can i find such examples. have searched alot but could not find it.

For example concept of Templates in C++ are for comfort as compiler generates some additional code, for your class or for your function, isn't it? So we could live without template by doing some additional (manual work).
What about virtual functions???
Are there any situations where both of them are irreplaceable?
I'm a newbie at networking. I understand the concept of multicast, but was wondering if it's reliable on the open/public internet?
It seems like sort of an edge case that different backbones or ISPs might intentionally break to reduce router load or generally segment the network for practical high-use applications.
Is my fear reasonable?
P.S. Follow-up question here:

Hi
I am interested by converting some code from C++ to C (mostly because i need to use the library with/from other C program and other language) . C is a better gateway for that
I am interested to replicate few C++ concept like inheritance for inst .
Does anyone know good references or has already work on some similar issues. For inst how to deal with inheritance , adding new members variable/ methods to child class , ...
Thx for your help
Today, I had a training on "Microsoft Workflow Foundation".
While I think the idea is neat, I still see it as a Proof Of Concept and not as a real-life solution. Building an entire application without having to type a single line of code (or only a few of them) seems just wrong.
Have you ever used this technology and if so, can it really fit to big company projects ? What drawbacks/advantages have you got using it ?
.Net defines a "Trace Source" concept, allowing configuration files to specify which trace sources to listen for messages on. WCF provides several trace sources, and I would presume that other portions of the .Net Framework BCL publish other trace sources as well. What is the list of trace source names published to by the BCL?
If you were a programming teacher and you had to choose one sorting algorithm to teach your students which one would it be? I am asking for only one because I just want to introduce the concept of sorting. Should it be the bubble sort or the selection sort? I have noticed that these two are taught most often. Is there another type of sort that will explain sorting in an easier to understand way?
I was reading an article on Batch Processing in java over at JDJ http://java.sys-con.com/node/415321 . The article mentioned using a persistence queue as a Batch Updater instead of immediately sending an individual insert or update to the database. The author doesn't give a concrete example of this concept so I googled Persistence Queue but that didn't come up with much. Does anyone know of a good example of this?

For the past few years I've been dabbling in object-oriented languages like Python and Ruby, but the OOP concept never really meshed with me. Right now, I'm eager to learn something based on a different paradigm.
Are there good example codes of implementations of factor graph sum-product scheduling? I am new to the concept, and would like to see how it gets implemented.
Hello,
Our current web application url reveals the class package structure to the end user. This is because in web.xml the servlet mapping tag is as follows
Servlet_ name
/servlet/com.xxx.yyy.ClassName
Is there any way by which i can hide the package structure. i.e com.xxx.yyy.ClassName to just ClassName?
Thanks

Rather a simple question. But the implications are vast.
Over the last few weeks I've been reading a lot of material about n-tier architecture and it's implementation in the .NET world. The problem is I couldn't find a relevant sample for Winforms with Linq (linq is the way to go for BLL right?).
How did you guys manage to grasp the n-tier concept? Books, articles, relevant samples etc.
How do I use the schema clause on a bag object in Nhibernate mapping? I have an table that I need to sepcify the schema for and the nhibernate documentation talks about table schema but I can't find any further details...
I have dictionary like
d = {'user_id':1, 'user':'user1', 'group_id':3, 'group_name':'ordinary users'}
and "mapping" dictionary like:
m = {'user_id':'uid', 'group_id':'gid', 'group_name':'group'}
All i want to "replace" keys in first dictionary with keys from second (e.g. replace 'user_id' with 'uid', etc.)
I know that keys are immutable and i know how to do it with 'if/else' statement.
But maybe there is way to do it in one line expression?
